It was a fun kayak ride to the bay to see the bioluminescence in the bay. Tour guides were great. Best to see when it’s a new moon. They provide a tarp to put over your head to see it. You need to be under 225lbs to ride so start dieting now. Luckily we all made the cut. Also make sure to bring flip flops or water shoes. Kayaking experience is useful but not required as many folks were paddling into the mangroves.

horrible customer service and they are very hard to work with. After booking the cruise the day of, they refused to help after they called and said that there was a weight limit and I did not see it on the website. They then proceeded to tell me that 3 of the 4 people of the group could still participate and the other could not and could either not show up or sit on the car. I should have seen that they had zero reviews and not booked with them.
